Rear-Facing: 5 – 40 lbs, a standing height of 49 inches or less and seated shoulder height of 9 – 16.75 inches. Forward-Facing: 1 year & 20, up to 70 lbs, a standing height of 49 inches or less and a seat shoulder height of 12 – 16.75 inches.

EZ-Buckle System retains the harness buckle in a forward position and prevents the child from sitting on the buckle when boarding

Base with SafeCell Technology features SafeCells designed to compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat which normally propels the child toward the front seat.

Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash.

Energy-Absorbing Versa-Tether features a staged-release tether webbing to slow the forward movement, reducing the crash forces reaching the child, and a two-point attachment to minimize forward rotation while anchoring the top of the child seat.

The MARATHON™ 70-G3 achieves revolutionary head safety through the use of BRITAX SafeCell™ Technology, Integrated Steel Bars, and Versa-Tether® that work together to minimize head excursion and reduce the risk of head injury during a frontal impact.

Britax is the Best!!!

August 6, 2013

Our little guy is now 10 months. He is 20lbs & 28in long. He fits beautifully in there with much room to grow.
Right now we have him rear facing so I haven't seen what he would look like forward facing. But the seat does
have three seat positions. We have a mini van and my husband can put the seat all the way back without the
seat interferring with the carseat. This is our second child and we have only used Britax carseat/boosters. We
love the safety, easy installation and comfort they provide.

Pros:

I bought this for my grandson. Absolutely the BEST. I would recommend it to keep anyones precious little one safe.

This is an excellent product. Light and easy to carry. User friendly when putting in vehicle. Lots of padding, strong straps that click into place easily. Durable. Once I took this out of the box I could tell just by looking at it that it was what I needed to keep my grandson safe. This convertible car seat is definately worth the little bit of added expense.

Cons:

NONE.

Love it!

May 6, 2013

At first I was intimated by a you can do and learning just how to do it, but once I learned how it became a breeze. Granted my son still hates getting in it 90% of the time (he hates that with any carseat) he does seem to relax, sleep better, and cry less on longer trips!

Pros:

Strong and comforable. Well made.

Cons:

A little bulky

Great Car Seat

February 19, 2013

My 11 month old loves this car seat. He was 4 weeks early and we had to purchase an infant care seat for the first couple months and recently switched to the Britax Marathon 70-G3 Convertible car seat. I love how it can expand to fit him as he grows. No complaints and Albee Baby has been great!

Britax car seat

February 14, 2013

We are the grandparents and we bought the seat for our granddaughter. She has only ridden in it so far and it was fine. The more we get to take her places, the more experience we will have with this car seat.

Pros:

Like the color and the look of it. My son-in-law put it in the car and it was an easy install as far as I could see.

Cons:

Nothing to complain about yet.

very pleased

October 19, 2012

we moved my son to this seat when he was around 20 months (he had a little sister on the way who was taking his old car seat). we have only used it facing forward. It is bulky but seems super comfortable to him. Also, I LOVE how easily the straps adjust up and down. Occasionally I will have my niece with me but not my son. She is MUCH larger and 18 months old than him (90% 4 year old) but it is an easy adjustment to move the straps up to fit her.
